The Appalachian Development Highway System (ADHS) was created to improve road transportation in the Appalachian region.

Established in the 1960s, the ADHS aimed to provide better access to remote areas, enhance connectivity between communities, and facilitate economic development. By constructing and upgrading highways, the initiative sought to reduce isolation in the Appalachian Mountains, promote trade, and improve access to healthcare, education, and employment opportunities. This development has had a lasting impact on the region's infrastructure and overall quality of life for its residents.
